Cheers for the report Matthias and SUSE Security! Could you please comment on the affectedness of upstream screen 5.0.1?
https://git.savannah.gnu.org/cgit/screen.git/commit/?h=screen-v5&id=464c8d8f945f53f8cbb854517279349e09d74756 This version was released ~an hour before your initial oss post. It appears that upstream landed the patches, which may be worth mentioning in your timeline. Kind regards, Mark
